HiDef, short for "high definition", also called 24P is a 24 frames-per-second digital video format for high-resolution capture of motion pictures. "24" refers to the frame rate - 24 fps, and the "p" stands for "progressive image scanning", (as opposed to "interlaced scanning.") There are currently two 24p HD formats, Sony 24p and Panasonic 24p.

Cameras of this capture depth have been available only in the last two years, most notably used by George Lucas for production of his second Star Wars movie, Attack of the Clones. The advantages of shooting with digital-capture cameras, is the efficiency in the production process; no transfer from film to digital is needed to edit scenes digitally, and if projected with a digital projector, no transference to film is required, also.
